Pinhole pupilloplasty is a method to reduce the size of a pupil to as small as a pinhole.
Pinhole optics have been used for various indications such as highly irregular astigmatism and corneal scar. Single-pass four-throw pupilloplasty has been shown to have good functional and anatomical outcomes for various indications including angle-closure glaucoma, Urrets-Zavalia syndrome (UZS) and post-corneal ectasia-induced aberropia. In this column, we would like to share our experience of post-keratoplasty cases wherein pinhole pupilloplasty has shown good functional outcomes.
